Prof. Dr. Catherine Dubourdieu heads the Institute “Functional Oxides for Energy-Efficient Information Technology” at HZB and is Professor at the Physical and Theoretical Chemistry division at Freie Universität Berlin. The physicist and materials scientist specialises in nanometre-sized functional oxides and their applications in information technologies. She has now been awarded a prestigious ERC Advanced Grant for her research project “LUCIOLE”, which aims at combining ferroelectric polar textures with conventional silicon technologies.
With its ERC Advanced Grant format, the European Research Council enables outstanding scientists to conduct pioneering and groundbreaking high-risk research. An ERC Advanced Grant is considered one of the highest awards for experienced researchers.
The project LUCIOLE focuses on ferroelectric nanometer-size oxides, which can host exotic polar textures such as vortices or skyrmions. With a wealth of potential emergent properties, whirling topological polar nanodomains could lead to novel devices, for example ultra-compact memories that store more than a terabyte per square inch. “We want to pave the way to future low power nanoelectronics based on topological defects” says Catherine Dubourdieu.
Monolithically integrated polar textures on silicon will be created and investigated on a nanoscale with state-of-the-art microscopy and spectroscopy techniques. These engineered polarization patterns will be embedded into ultra-scaled devices to study their manipulation and dynamics under electric field.
"We have known about the phenomenon of ferroelectricity for a good hundred years. But it is only in recent years that exotic polar textures have been unveiled. This opens up exciting possibilities for revolutionary new materials and devices. This is definitely the best time to be at the forefront of this field of research," says Dubourdieu.

With ERC Grants, the European Research Council supports outstanding scientists who want to implement risky but potentially groundbreaking research ideas. An ERC Advanced Grant is considered one of the highest awards for experienced researchers.
- Helmholtz Doctoral Award for Hanna TrzesniowskiDuring her doctoral studies at the Helmholtz Centre Berlin, Hanna Trzesniowski conducted research on nickel-based electrocatalysts for water splitting. Her work contributes to a deeper understanding of alkaline water electrolysis and paves the way for the development of more efficient and stable catalysts. On 8 July 2025, she received the Helmholtz Doctoral Prize, which honours the best and most original doctoral theses in the Helmholtz Association.
- New department at HZB: ‘AI and Biomolecular Structures’Since 1 July 2025, Dr. Andrea Thorn has been setting up the new AI and Biomolecular Structures department at HZB. A biophysicist with many years of experience in AI-based tools for structural biology, she is looking forward to collaborating closely with the macromolecular crystallography team at the MX beamlines of BESSY II.
